cartValidateDiscountCode

Preview whether a discount code is currently applicable to a cart — read-only, no cart side effects. Use for inline feedback while the buyer types a code, before calling cartDiscountCodesUpdate. Result depends on the cart subtotal (minimum-order rules) so do not cache aggressively: prefer fetchPolicy: "network-only" or include cart.subtotal in the cache key.
